Hi!

Try following:

DECLARE INTEGER FindMimeFromData IN ??? integer pBC, ;
string @pwzUrl, string @pBuffer, integer cbSize, string @pwzMimeProposed,;
integer dwMimeFlags, string @ppwzMimeOut, integer dwReserved

If you want to use NULL value for pwzUrl, pBuffer or pwzMimeProposed parameters, declare these parameters as integer type and pass zero to function. I'm also not sure about ppwzMimeOut parameter. If it is double-pointer, you will require to use the API functions to allocate the memory for that parameter.

HTH.

P.S.
Well, if you meant the file type of the disk file in Windows, it is determined by Windows using the file extension. And I do not remember any function that verifies if, for example, '.DBF' file really is not a text file. As about the FindMimeFromData function, it just "Determines the MIME type from the data provided." as I see in the MSDN help. If you meant something else, well, be more exact in your questions next time.
